Lockheed Martin [NYSE: LMT] announced that the latest version of Radiant Mercury, a system that allows sharing of sensitive data between differing security domains, has been approved for both Top Secret and Secret interoperability by the Unified Cross Domain Management Office. This office provides centralized coordination and oversight of all cross domain initiatives across the Department of Defense and the Intelligence Community.

"Radiant Mercury enables sensitive information to be shared during critical missions," said Jim Quinn, Vice President with Lockheed Martin's Information Systems & Global Solutions-Defense. "We will continue to evolve the system to ensure that it provides the most robust capabilities available in the environments in which our customers operate."

Radiant Mercury incorporates a suite of high-assurance, trusted technologies that "guard" classified and sensitive data from unauthorized access while allowing government intelligence agency networks to transfer documents among groups operating at various security levels. This latest version of Radiant Mercury can process hundreds of data formats at speeds up to 10 times faster than previous versions.

The system supports simultaneous data flows to hundreds of channels, interfaces with most major C4ISR systems, and supports most transport, network, and data link protocols. It also ensures data and communications coming from one network domain to another undergo extremely high levels of scrutiny to protect against compromises of information.

Since developing the system in 1992, Lockheed Martin has continued to upgrade the system to meet the operational needs of customers throughout the world. Accredited at the highest level of protection in the United States for secure information sharing, Radiant Mercury supports U.S., coalition, and international partners at more than 400 sites worldwide.

Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 133,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The Corporation's 2009 sales from continuing operations were $44 billion.
